Conditions & Diseases: Brain & Nervous SystemEncephalitisSee Also: Medical Tests & Diagnosis Methods/Tools Diagnosis of encephalitis is done with the help of the following:
Blood and Urine Tests: These tests help isolate and identify the viruses. Enzyme-linked immunosorbent assays (ELISA), including IgM-capture ELISA (MAC-ELISA) and IgG ELISA can help identify the virus causing encephalitis. Polymerase chain reaction (PCR) helps in identification of small amounts of viral DNA. Imaging Tests: Imaging tests consist of Computed Tomography (CT scan) and Magnetic Resonance Imaging (MRI scan) producing computer images of the brain which help in detecting abnormalities like swelling (edema) and bleeding (hemorrhage). In Electroencephalogram (EEG), electrodes placed on the scalp are used to record and analyze the electrical activity in the brain. Wave patterns thus recorded suggest seizure disorder or specific viral infection. Spinal tap: In this procedure, cerebrospinal fluid is collected by inserting a needle between two vertebrae in the lower spine. The fluid is analyzed for an elevated count of White Blood Cells (WBC), blood and presence of virus (9). See Also:
